This is an extension of the Plessey code. The Plessey specification sets out the encoding scheme for
numeric data, but leaves the other bar combinations open. This is the most common use of the open
combinations - to encode the letters A through F, allowing the use of Hex notation to represent 0-255
in a two character combination.
